Lunar Chronograph Aurora

Independent Swiss watchmaker Armin Strom proudly presents the Gravity Equal Force Ultimate Sapphire Rose Gold, a timepiece that exemplifies the brand’s commitment to horological innovation, artisanal craftsmanship, and visual harmony.

Encased in 18K rose gold, this limited-edition watch features a sculptural movement architecture that plays with tone and texture. A brown guilloché mainplate, rose gold-colored bridges, and a floating off-centre sapphire dial create a refined and coherent composition. The watch is paired with a matte brown nubuck leather strap, adding an earthy elegance to the overall aesthetic.

At the heart of the timepiece is the Caliber ASB19, Armin Strom’s groundbreaking automatic movement. It incorporates a patented stop-work declutch mechanism and Geneva cross within the barrel, ensuring consistent torque delivery throughout its 72-hour power reserve. A micro-rotor enables efficient winding while preserving the symmetry and visibility of the movement — a hallmark of Armin Strom’s design philosophy.

Every component, visible or hidden, is hand-finished to haute horology standards. Techniques such as beveling, straight-graining, perlage, Geneva stripes, and black-polished screws are applied with precision and care. The mainplate features a “grain d’orge” guilloché pattern, crafted by master artisan Kari Voutilainen using a traditional hand-operated machine.

This exceptional timepiece is limited to just 25 pieces per year, making it a rare and radiant statement in the world of independent watchmaking. It is a testament to Armin Strom’s philosophy: Mechanics First. Always.

Armin Strom unveils its latest horological creation, the Dual Time GMT Resonance Manufacture Edition Blue, strictly limited to just 50 pieces worldwide. Drawing from classical watchmaking codes, this exceptional timepiece introduces a subtle retro-chic character through a deep blue PVD-coated mainplate and gear-train bridges. Positioned directly on the dial side, the vibrant blue execution elevates open-worked architecture to new heights, delivering a visually captivating contrast that redefines traditional hand-finishing.

The aesthetic composition centers around two finely grained white dials, each adorned with white azurage chapter rings that catch the light while revealing the rich blue mainplate underneath. Accentuating the design are blue PVD-coated applied indexes and facetted polished hands that echo the hue of the underlying movement. Each display is paired with a black-polished day/night disc depicting sun rays and a uniquely crater-textured crescent moon, while a matte dark blue alligator leather strap with white stitching seamlessly ties the entire color palette together.

At the heart of the timepiece beats the in-house manufacture Calibre ARF22, a manual-winding movement engineered to harness the physical phenomenon of resonance. Utilizing Armin Strom’s patented resonance clutch, two independent regulating systems oscillate in perfect synchronicity, delivering heightened chronometric precision and an enthralling three-dimensional kinetic display. Providing intuitive functionality for global travelers, the movement powers two completely independent time zone displays—each with its own hours, minutes, and day/night indication—operating at a frequency of 3.5 Hz (25,200 vph) with a 42-hour power reserve.

Housed in a compact stainless steel case measuring 39.00 mm in diameter and 9.05 mm in height, the watch offers refined ergonomics alongside a water resistance of 5 ATM. The double sapphire crystal construction reveals exquisite decorative detail on both sides, including laser-engraved relief lettering on the reverse mainplate, bright polished bevels along the blue bridges, and rhodium-colored barrel bridges adorned with classic Côtes de Genève.

Haute Horlogerie Dominique Renaud (HHDR) marks its official debut with the launch of the Pulse60, unveiled in preview at the Time To Watches fair in Geneva (April 14–19, 2026). This first creation of the new Dominique Renaud brand introduces a radical approach to low‑frequency mechanical watchmaking and expresses the purest form of Renaud’s watchmaking philosophy.

A Vision Rooted in First Principles
Dominique Renaud, co‑founder of the legendary Renaud & Papi manufacture and creator of numerous landmark complications, returns with a renewed focus on foundational movement principles. Guided by the maxim “form ever follows function,” his work embraces clarity, purity and a minimalist, self‑evident aesthetic.
The establishment of HHDR in Tolochenaz brings together a team of watchmakers, designers and engineers in a collaborative, idea‑driven environment. HHDR is conceived as a living laboratory — a place where experimentation, shared expertise and long‑term exploration shape new forms of contemporary horology.

Pulse60 — A New Mechanical Language
At the heart of the Pulse60 is the newly developed BUA2024 movement, which embraces an ultra‑low 1 Hz frequency — just one oscillation per second, echoing the natural rhythm of the human heart. This approach reduces escapement shocks and disturbances, transforming time measurement into a slower, more embodied rhythm.

To master this low frequency, the movement features a monumental 20 mm high‑inertia balance wheel, inspired by marine chronometers. Its large moment of inertia stabilizes the rate by absorbing minute variations in energy and motion.

Dominique Renaud has also completely reimagined the regulating organ, allowing amplitude greater than 360° without knocking, with a theoretical range reaching approximately 700°. This unprecedented freedom greatly improves static rate stability by allowing the balance to follow its own natural dynamics over a longer portion of its oscillation.
 

A Design That Expresses Its Mechanics
The Pulse60’s innovative mechanics are reflected in its seamless, fluid architecture:

- A domed crystal with no bezel
- Lug‑less construction and integrated strap
- Three‑part case structure
- Diamond‑cut or guilloché dial details
- A patented offset regulation system placed outside the balance wheel, offering a completely unobstructed view of the slow‑beating 1 Hz oscillator

The display includes an hour‑minute dial at 12 o’clock, a natural dead half‑second at 9 o’clock, and a torque indicator at 3 o’clock. The caseback reveals a minimalist composition of circular and linear forms, framing the openworked escapement line and double‑roller assembly.
